LTS-10304/10804 Description The LTS-10000 series are 1.0 inch (25.4mm) height seven segment single digit displays. The Displays have black face and white segment. The AlGaAs red seven segment displays are designed for applications requiring low power consumption. They are tested and selected for their excellent low current characteristics to ensure that the segments are matched at low current. Drive current as low as 1mA per segment isavailable. The AlGaAs red series device utilize LED chips which are made from AlGaAs on a non-transparent GaAs substrate. The bright red and green series devices utilize LED chips which are made from GaP on a transparent GaP substrate. The yellow and red orange series devices utilize LED chips which are made from GaAsP on a transparent GaP substrate. Notes:All dimensions are in millimeters (inches). Tolerance: 0.25mm (0.01") unless otherwise noted.
